Halyard is the tool responsible for managing your Spinnaker deployment’s lifecycle. This includes writing & validating your deployment’s configuration, deploying each of Spinnaker’s subcomponents, and performing updates to your deployment of Spinnaker.
All non-quickstart deployments of Spinnaker require Halyard to manage configuration, installation, and updates of Spinnaker. While it is possible to install Spinnaker without Halyard, we do not recommend it, and if you get stuck we will encourage you to instead use Halyard.
There are a few different ways to install Halyard (with more on the way):
The following command installs the latest released Halyard version, and will prompt the user for some configuration in the process. Generally the default answers to each prompt are best.
curl -O https://raw.githubusercontent.com/spinnaker/halyard/master/install/stable/InstallHalyard.sh sudo bash InstallHalyard.sh
At this point, run the following command to see if Halyard was installed properly.
If that command fails, make sure
hal is in your
$PATH, and check for logs
This installation path is in alpha and will have some rough edges.
Make sure you have Docker CE installed.
Fetch the latest Halyard version:
docker pull gcr.io/spinnaker-marketplace/halyard:stable
Make (on your current machine) a local Halyard config directory. This will persist between runs of the Halyard docker container.
Now, run the Halyard docker container, while mounting that Halyard config directory for your container:
docker run -v ~/.hal:/root/.hal gcr.io/spinnaker-marketplace/halyard:stable
This will emit all of the Halyard daemon’s logs, and run as a foreground process in your current shell.
In a separate shell, run:
docker exec -it <id of halyard container> bash
Now you’re able to interact with the Halyard daemon. However, any
secrets/config you need to supply to the daemon (e.g. a kubeconfig file) will
need to be mounted in either your local
~/.hal directory, or another
directory that you supply to
Command-Completion & Help
If you’re ever stuck, appending
-h to a command will provide some help text
to explain what a command does. If you’re still stuck, try looking under the
Halyard also supplies a fair amount of command-completion; if you haven’t already, run the following command or restart your shell to enable it.
You can always update Halyard by running the following commands.
sudo apt-get update sudo apt-get upgrade spinnaker-halyard
If you’ve used Halyard to deploy Spinnaker, and want to first purge that deployment, run the following command.
hal deploy clean
At this point you can safely uninstall Halyard by running the following command.
Once Halyard is installed and running, it’s time to decide which environment to deploy Spinnaker to.
